Starring 'Fringe''s Jackson, ‘The Wire‘ vet Dominic West, ‘E.R.”s Maura Tierney and Ruth Wilson, Showtime's new 10-episode drama 'The Affair' explores the two marriages affected by the titular affair between West and Wilson's characters, as well as the resulting fallout that ensues over a period of years. Set to premiere on October 19, the series was created by ‘In Treatment”s Sarah Treem and Hagai Levi. Treem wrote the pilot to feature both the male and female perspectives, while both Treem and Levi will executive produce alongside director Mark Mylod (‘Shameless‘).

Meanwhile, the tragic loss of Philip Seymour Hoffman influenced Showtime never to air the pilot shot with Hoffman in the leading role, though network boss David Nevins has quietly reached out to A-list actors to potentially replace the 'Hunger Games' star. “I’m sitting on five scripts from (creator) Shalom Auslander that I think are brilliant,” said Nevins. “If we cast it the right way, I would make it.”

Previously titled 'Trending Down,' Showtime's ‘Happyish’ was described as “a blistering attack on our youth-obsessed culture and a darkly comic examination of what it means to matter. Or matter not." Hoffman played the leading role of Thom Payne, a Prozac and Viagra user who finds himself adrift when his advertising agency is taken over. Kathryn Hahn played Payne’s wife Lee, while 'Amazing Spider-Man' star Rhys Ifans portrayed Payne’s boss.

Sad as it is to lose Hoffman in the role, and in general, we'd be open to seeing 'Happyish' resurrected down the line, while 'The Affair' has generated an impressive amount of buzz, even before its trailer.
